' ATTORNEYS flue/ 5 EBaum/ lubricant to the rotatable cup; Fig. 5 is a rrnn ermine Arena enrich.

To aZZ whom it may concern:

Be it known thatwe, AnoUs'r Sononnand ALBERT E. BAUM, citizens of f the United States of America, and residents of'Water- 100, in the county of Blackhawk, State of Iowa, have invented a new and Improved Oiler, of which :the following is a full, clear, 7 and exact description. a

Our invention hasfor its object to provide an oiler, and one particularly well adapted for use on windmills, having a member adapted to be raised by a pitman on a windmill, and against the tension of a spring, this member being connected with a rotatable member by means for operating the latter, the rotatable member having operating means for pumping a lubricant to a rotatable cup, having a spout for supplying a plurality of conduits with the liquid, and there being also means by which the r0ta. table member will rotate the cup.

Additional objects of the invention will appear in the following complete specification, in which the preferred form of the invention is disclosed; I

In the drawings similar characters of reference indicate corresponding parts in all the views, in which Figure 1 is a view showing a portion of a windmill to Which our oiler is attached; Fig. 2 isa side elevation of Fig. 1; Fig. 3 is an enlarged sectional elevation of the oiler; F ig. at is a sectional view similar to that shown in Fig. 8' but with parts broken away to show the means for pumping the sectional fragmentary view of the oiler look ing at the devicefrornthe rear; Fig. 6 is a side elevation of Fig. 4; Fig. 7 is a side elevation of Fig. 5'; and Fig. 8 is a plan view of Fig. 3. i '7 7 Most of the windmills which have been in use for several years areiso badly worn that it is diflicult to connect with them any of the oilers now in use in such amanner as will insure an even and certain feed of the lubricant at all times. This fault is entirely removed with our oiler, as it is operated by a member secured to the pitman of the wind mill, and which, with the operation of the said windmill, will be raised periodically, to strike and raise a member of the oiler for operating the latter, the said member of the oiler being held yieldingly downward by a spring. s the pitman member and the Specification or Letters Patent.

oiler member may have extending horizontal surfaces it will be seen that the oiler is certam to be operated with the reciprocation of the pitman. .Thelposition of the member secured to the pitman may be adjusted relatively to the pitman, and in this way the distance of the upward 'movement of the may-be regulated.

By referring to the. drawings it will be seen that a casing 5 is mounted on a bracket tending member 16 ,for holding the memberv 14 yieldingly downward The upper -portion of the member 14; is bent over at 12, and extends down through an opening in the top 13, of the casing, and also through a tube 18, the lower terminal 19 of this bent portion 12 having pivoted to it a pawl 20, which is adapted to engage the teeth 21 of a gear.

wheel 22, this gear wheel 22-being mounted to rotate on a stud 23, secured to a standard 24: within the casing 5. It will be seen that with this construction when the horizontally extending member 16 is engaged by the horizontally extending portion 25 of the mem ber 26, which is carried by the pitman 27 of the windmill, it will be pushed upward, carrying withit the bent portion 12 and its terminal 19, which will move the pawl 20 upward, and in engagement with one of the teeth 21 to rotate the wheel 22. The'wheel 22 isiprevented from rotating when the pawl. I 20 is moved downward with the member l t by the'pawl 28, pivoted to the standard 2%. Secured to the wheel 22 there is a cam 29,

oiler member and the operation ofthe oiler on which is'mounted the pawl 3O,- the pawl V 30 having an opening 31, in which the cam 29 is disposed. It will therefore be seen that with the rotary movement of the wheel 22, and its cam 29, the pawl 30 will be reciprocated, this pawl 30 engaging the teeth 33 of a wheel 34, mounted on an arm 35, ex?

tending from the standard 24:. This'wheel I 34: rotates in only one'direction, and it is prevented from rotating the opposite direction by means of the pawl 36, which engages its teeth 33, this pawl 36 being pivoted to the standard 24.

It will be seen that the wheel 22 will be rotated intermittently by the reciprocating movement of the member 14, and it will also be seen that the wheel 34 will be rotated intermittently by the rotation of the wheel 22,

and the pawl 30 mounted on the cam 29.'

This wheel 34, which will have a Very slow and intermittent movement relatively to the movement of the windmill, serves as a means for distributing the lubricant, which is contained within the casing 5. The lubricant passes through a lateral opening 37, to the conduit 38, in the member 39. This conduit 38 has a terminal 40, through which is disposed a plunger 41, this plunger 41 extending through an opening 42, in an arm 43, secured to the standard 24, the plunger being provided with a wing 44, which is adapted to be engaged and be raised by a pin 45, on one face of the wheel 34, the plunger 41 being held normally downward by the spring 46, which engages the arm 43, at one end, and presses against the wing 44, at the other end. The conduit 38 has another upwardly extending terminal 47, in which is secured the lower terminal 48 of the lubricant supply pipe 49, there being. a check valve 50 in the said terminal 47 below the lower terminal 48 of the lubricant supply pipe. This lubricant supply pipe extends upward in a sleeve 51-, which is mounted to rotate in an opening 52, in the top 13 of the casing. The said sleeve 51 is connected with the cup 53, disposed above the top 13 of the casing. The lubricant supply pipe 49 not only passes through the sleeve 51, but also through an opening 54 in the cup. The upper terminal of the lubricant supply pipe 49 is bent over at 55, so that it will feed the lubricant into the cup. To the sleeve 51 and below the top 13 of the casing there is secured a horizontal ratchet member 56, with which engages a pawl 57, on an arm 58 of a lever 59, fulcrumed to the arm 60, which is secured to the standard 24, the other arm 61 of this lever 59 being engaged at intervals "by the pin 62, which projects from the wheel 34, this pin 62 projecting in a direction opposite to the direction in which the pin 45 projects from the said wheel 34. The horizontally disposed ratchet wheel 56 is held yieldingly in position so that it will be operated by the pawl to the best advantage, by a spring 63, which is disposed around the sleeve 51, the upper terminal of this spring 63 pressing against the bottom of the top of the end of the casing, and the lower end of this spring 63 pressing against the ratchet wheel 56. It will thereto-re be seen that with the rotation of the wheel 34, the pin 45 will at intervals raise the wing 44, and with it theplunger 41, to permit the lubricant to flow through the opening 37 into the conduit 38, and that when this plunger 41 is again moved down by the spring 56, the lubricant will be forced through the lubricant supply pipe 41, and its terminal 55, to the cup 53. It will also be seen that with the rotation of the wheel 32 the pin 62 will, at predetermined intervals, oscillate the lever 59, which will, by means of the pawl 57, rotate the ratchet wheel 56, a predetermined distance, and with it the cup 53. This cup 53 has an elongated spout 64, which rotates with the cup, and is adapted to supply the lubricant to each of the plurality of conduits 65, which feed the lubricant to the pipes 66, which lead to the several bearings and other parts of the windmill, which it is necessary to lubricate.

A spring 61 is provided for connecting the arm 61, of the lever 59, with the lug 68 on the standard 24, this spring serving to hold the lever 59 yieldingly in position, to be engaged by the pin 62 on the wheel 34. The member 26 is carried by the pitman 27 of the windmill by a clamp 69, which is secured to the pitman 27, and which has a cup member 0, and projecting therefrom a member 71, having a threaded opening 72, through which the member 26 which may be a rod, extends. This member 26 has its lower terminal 73 threaded, this threaded terminal extending into the threaded opening 72. A nut 74 meshes with the threaded terminal 73 below the projection 71, to hold the member or rod 26 in position, after it has been adjusted. It will be seen that this member 26 may be raised or lowered relatively to the pitman 27, and may be secured in this adjusted position by the nut 74. By this means the distanceof the movement of the 'member or rod 14 may be regulated. When the member or rod 14 moves a relatively longdistance, it will, by means of the pawl 20, rotate the wheel 22 a greater distance at each upward movement of the member or rod 14, than will be the case when the member or rod 14 moves upward a rela-' tively. short distance. The oil cup is preferably filled with hair for receiving the lubricant from the lower terminal of one of the pipes 66, when the pitman is raised, the oil passing from this cup 70 through the pipe 75, to any cup or mechanism which may be mounted on the pitman 27.
